TSM Snapdiff backup and usage of Snapdiffchangelog in Stagingdirectory

First concerns is with the stagingdirectory itself. In documentation for BA client (7.1.3) is the following
statement:
"The stagingdirectory option defines the location where the client can keep any
data that it generates to perform its operations. The data is deleted when
processing is complete."
It's unfortunately not true in case of snapdiffchangelog, as this file is kept permanently.
Above that it's very sensitive file for the next incremental snapdiff backup.

Second point is the snapdiffchangelog file. There is no single explanation of this file in the official documentation. We found-out the file is sensitive and in case of lost or corruption, the new initial backup must be completed (which can generate issue on very large filers like several days of backup ). This is not good, if the TSM is not able to recover the file itself in combination with the previous point.
